DMCA and Copyright

Last updated: October 2026

CommunityCAD respects the intellectual property of others and expects its users to do the same. We respond to notices of alleged copyright infringement under the US Digital Millennium Copyright Act (DMCA). We also act on clear reports of infringement from anywhere.

You don't need an account to send a notice.

Quick removal of imported models#

Some models on CommunityCAD were imported from public GitHub repositories. If one of them is yours and you'd simply like it removed, you don't need a formal notice: email contact@communitycad.dev with the link, and we'll take it down.

Sending a takedown notice#

Send your notice to our designated copyright agent:

Copyright Agent, CommunityCAD Email: contact@communitycad.dev, with "DMCA notice" in the subject line

Your notice must include:

  1. your physical or electronic signature (typing your full name is fine by email);
  2. identification of the copyrighted work you say is infringed (or, for several works, a representative list);
  3. identification of the material on CommunityCAD you say infringes, with enough detail for us to find it. The link to each model, comment or post is best;
  4. your contact information: name, postal address, telephone number and email address;
  5. a statement that you have a good-faith belief that the use is not authorised by the copyright owner, its agent, or the law;
  6. a statement that the information in the notice is accurate, and, under penalty of perjury, that you are the copyright owner or authorised to act on their behalf.

What happens next#

  • We review the notice and, if it's complete, remove or disable access to the material promptly.
  • We notify the uploader, including a copy of the notice (with your contact details, as the law expects, so they can respond).
  • Removed models show "Model removed".

Counter-notices#

If your material was removed and you believe that was a mistake, or that you have the right to use it, you can send a counter-notice to the same address. It must include:

  1. your physical or electronic signature;
  2. identification of the material removed and where it appeared before removal;
  3. a statement, under penalty of perjury, that you have a good-faith belief the material was removed as a result of mistake or misidentification;
  4. your name, address and telephone number, and a statement that you consent to the jurisdiction of the federal district court for your address (or, if you're outside the US, any judicial district in which CommunityCAD may be found), and that you'll accept service of process from the person who sent the original notice or their agent.

We forward valid counter-notices to the person who sent the original notice. Unless they tell us within 10 business days that they've filed a court action to stop the infringement, we may restore the material within 10 to 14 business days after receiving the counter-notice.

Repeat infringers#

We close the accounts of users who repeatedly infringe copyright, in appropriate circumstances.

Misrepresentation#

Under the DMCA (17 U.S.C. § 512(f)), anyone who knowingly makes a false claim in a notice or counter-notice can be liable for damages. If you're not sure whether something infringes your rights (for example, whether a use is licensed or fair), consider getting legal advice before sending a notice.

Other rights#
